windows 7 professional softwares - mail.yahoo does not operate properly - works ok on ie 9.0.8112.16421

I use yahoo mail. This problem started about a week ago. I just loaded the 19 beta version with no help. The picture YAHOO1 is using Firefox and picture YAHOO2 is using IE 9.0. With IE I have the the Move - Delete etc functions. How do I post print screen .gif files.

With Firefox I do not get the Move, Delete, Forward etc functions. These functions work fine with IE 9.0
